LOCK;

Specification of Letters Patent.

Application filed August 14 1911.

PatentedNov. 25,1913. Serial no. 643,853.

To all "whom it. may concern:

.Be it known. that I, RICHARD J. KEPPEL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inLocks, cation.

My invention relates to improvements in looks, and more particularly tolooks designed for use in connection with china closets and othersimilar articles of furniture, which is adapted to hold the latch in itsholding position, or release thelatch as may be desired.

A further object is to providealock of this character which may be madefrom sheet metal, which will be comparatively cheap to manufacture, andwhich may be used inconnection with any ordinary formv of pivoted latchto maintain the latch in. its holding position, or permit the latch tomove.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangementsof-parts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings: Figure 1, is a view in vertical sectionillustrating my improvements. Fig. 2, is a face view of the lock. Fig.3, is a view of the lock with the face plate removed, showing thetumbler in unlocked position. Fig. 4, is a view similar to Fig. 3showing the tumbler in locked position. Fig. 5, is a View similar toFig. 2 showing a modification, and Fig. 6, is a view of the key.

1, represents a door which is provided with two openings 2 and 8, theopening 2 being preferably directly above the open ing 3.

4, represents an escutcheon plate which extends over both the openings 2and 3, and has an integral handle 5. The escutcheon plate 4: at theopening 3 is provided with perforated ears 6 in which a pin 7 issecured, and serves as a fulcrum for a latch 8, and a coiled spring 9positioned on the pin normally presses the inner end of the latchdownward, and this inner end is, hook shape as shown, and adapted to engage a keeper 10 when in locked position, Escutcheon plate 4, oppositethe upper Of which the following is a specifiopening 2, is provided witha swiveled slotted key receiving plate 11, and through this plate a key12 is. adapted to-be inserted 5130 operate my improved lock which willnow be described.

13,, represents the casing of my improved lock,-and 14; a face platewhich is riveted to thecasing and extends beyondthe ends of the casingwhere it is provided with openings 15 for the reception of screws16 tosecure thelock to the inner face of the door.

The faceplate 14,.and alsothecasing 13, are provided in their lower.endswith registering slots .17 through which the latch 8 projects, andis normally movable up and downto engage or disengage the keeper 10. Toprevent the upward movement of the latch, a tumbler 18'is provided incasing 13, and has rotary mounting ona Stud 19. A bow spring QOengages afiat face 21 of the tumbler, -so as. to hold the latter in either of itspositions. This is accomplished by reason of. the fact thatthe spring isbent between its ends, and ,the bent. portion is centrally positioned onthe fiat face of the tumbler, and the tumbler on its flat face isprovided centrally with a slight. enlarge- 1 ment 22, which rides overthe bent portion of the spring, and holds the tumbler against accidentalmovement. The tumbler 18 is recessed in its lower edge as shown at 23,and thlSLI'GCQSS normally registers with the slots 17 so as not tointerfere with the movementof the latch. At one side of this recess 23,a shoulder 24-is provided which isvadapted when moved across the upperedge of, the latch to rigidly hold the latch against upward movement,and hence securely lock the door. To move the tumbler, the key 12 isprovided, and the tumbler is made with recesses'25 and 26 at oppositesides of a central lug 27 in the upper portion of the tumbler. One sideof this tumbler, which constitutes one wall of one of the recesses, ismade with an inwardly projecting shoulder 28 which serves to limit themovement of thekey in one direction, namely, in the direction to unlock.This is important, because it holds the key in a horizontal positionwhen unlocked, so that ample room is provided between the key and theouter end .of the latch for the insertion of. the thumb to depress thelatch. To prevent moving the tumbler, except by the proper key, the faceplate 14 is made with cient to enter the recesses 31 and the side movedinto the path of movement of the single pair of these notches as shownin Fig. 5, and hence the key can only be withdrawn 'ing openingsregistering with both opena key receiving opening 29 of a peculiarshape. In other words, a circular opening is provided and a series ofradially projecting recesses 30, and in forming these recesses the metalis bent at right angles, constituting lugs31 which are forced into theopening 2, and serve to center the lock.

The key 12 is provided at its inner end with an extension 32 adapted toenter an opening 33 in the lock casing 13, and turn therein. The widthof the key is just suffiedges of this key is notched as shown at 34: topermit it to turn. The recesses 31 are so located that the key may bewithdrawn in either its looking or unlocking position. It may bedesirable, however, to provide but a when the door is locked. It willtherefore be noted that my improvements enable the ordinary spring latchto operate as a lock, and the combined latch and lock can be acomparatively low cost, resulting in an improved construction, when inuse, over the ordinary forms of independent latch and lock. WVhile Ihave described the same as particularly adapted for use on a chinacloset, it may of course be put to various other uses, and I do notlimit myself to the precise details set forth, but consider my- 1 selfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

f 1. The combination witha door having two openings therein, of apivoted latch projecting through the lower opening and extending beyondthe inner face of the door, a lock casing secured to the inner face ofthe door independent of the latch and having openings registering withboth openings in the doon'said latch projecting through the loweropenings in the look, a tumbler mounted in the casing and adapted to belatch, and a key adapted to be projected through the upper openings inthe door and lock and operate said tumbler, substantially as described;

2. The combination with a door having two openings therein, of a pivotedlatch projecting through the lower opening and extending beyond theinner face of the door, a lock casing secured to the inner face ofthe'door'independent of the latch and havings in the door, said latchprojecting through the lower openings in the lock, a tumbler mounted inthe casing and adapted to be moved into the path of movement of thelatch, a face plate on said casing having an opening therein, and keyreceiving recesses at opposite sides of said opening, a key constructedto operate said tumbler, and notches in opposite sides of said key tore- -ceive the face plate between the recesses therein, substantially asdescribed.

3. The combination with a door having two openings therein, of a pivotedlatch proijecting through the lower opening and ex- ;tending beyond theinner face of the door, a lock casing secured to the inner face of thedoor independent of the latch and hav- 1 ing openings registering withboth openings lin the door, said latch projecting through the loweropenings in the lock, a tumbler .mounted in the casing and adapted to bemoved across the path of movement of the :latch, a face plate on saidcasing having an 7 manufactured and placed on the market at 25' openingtherein, and key receiving recesses at opposite sides of said opening, akey constructed to turn said tumbler, and notches in opposite sides ofsaid key to receive the face plate between the recesses therein, and

a sprmg within the locked casing bent between its ends and bearingagainst the tumbler, whereby said tumbler is held in either its lockedor unlocked position, substantially as described.

4:. The combination with a door having two openings therein, of anescutcheon secured to the outer face of the door and positioned over theopenings, a handle on said escutcheon, a latch pivoted to the escutcheonj and projected through the lower opening, a lock casing secured to theinner face of the :door independent of the latch and having an openingthrough which said latch pro- I jects, lugs struck from the face plateof said icasing forming key receiving recesses, said :lugs positioned inthe upper openingin the door, a swiveled slotted key receiving plate inthe escutcheon opposite the upper opening, a tumbler in said casing, anda key adapted to be projected through the upper opening to move saidtumbler into bon'tion over the latch and limit the movement of thelatch, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
